LAMP-BURNER.

srncrrIcArroN forming para af Letters raient No. 413,704, dated october 29,1889.

Application led July 5, 1889.

To all whom it may concern.-

jections formed in the wick-tube below the adjustin g-wheels, whereby the opening of the wick-'tube is contracted immediately below the wheels, and the wick is held against further downward movement'as soon as the wheels lose a iirm gripv on the wick.

My invention consists, further, of a projection which prevents the wick from interfering with the rotation of the wheels, as will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is `a sectional elevation of the lower portion of a Vtubular lantern provided with my improved burner. Fig. 2 is a sectional elevation of the burner. Fig. 3 is a similar view at right angles to Fig. 2. Fig. 4 is a horizontal section in line @c Fig. 2.

Like letters of reference refer to like parts in the several figures.

A represents the shell of the burner, B the burner-cone, and C the iiat wick-tube.

D representsthe spindle or shaft of the wick-adjuster, and L d the toothed .wheels thereof. The spindle is arranged outside of the wick-tube and journaled in' openings in the shell A. The wheels d cl project into.

the wick-tube through vertical slots e, formed in one of the broad walls of the tube.

ff represent projections formed on the inner side of the opposite wall of the wick-tube facing the toothed wheels and slightly below the same, so as to contract the wick-tube immediately below the wheels. These proj ections are preferably formed by indenting the wall of thewick-tube from the outside, as represented in the drawings.

When the Wick has been turned down so Serial No. 316,549. (No model.)

far that the toothed wheels have lost their the wick-tube below the wheels, caused by the projections ff, prevents the vwick from dropping down through j the wick-tube into the oil-pot, but holds the upper end of the wick A in contact with the lower portions of the wheels, as represented in Fig. 2, so that by wick-adjuster the wick cannot beturned down out of reach of the wheels. Upon turning the wheels in, an opposite direction, so as to raise the wick, the teeth of the wheels resume their grip upon the wick, overcome the slight resistance offered by the projections, and move the wick upwardly.

g is a projection formed on the wick-tube between the slots e, through which the wheels project, for the purpose of preventing the would cause the wheels to be obstructed, so as to render their rotation difiicult or impossible. The projections f facing the wheels tend to crowd the wick against these slots, and the proj ection g holds the wick away from the slots and prevents any interference with the free working of the wheels.

In aburner provided with my improvement the wick-adjuster can be turned freely without danger of losing the wick, thereby doing away with the necessity of observing carefully how far the wick is turned down. My vimprovement is extremely simple in construction, and can be applied to burners at triiiing' expense.

I claim as my invention- 1. The combination,with the wick-tube and the wiokadjusting wheels, of projections which extend into the wick-tube below said wheels and contract the tube, whereby the wick is prevented from dropping out of reach of the wheels in turning it down, substantially as set forth.

2. The combination, with the Wick-tube having slots in one of its walls for the wickadjusting wheels and the wick adjusting wheels projecting into the wick-tube through posite wall of the wick-tube and extending linto the wick-tube below said wheels, substantially` as set forth.

3. The combination, with lthe wick-tube iirm grip upon the wick, the contraction of' vunskillful or careless manipulation of the these slots, of projections'formed on the op wick" from being forced into the slots, which IOO having slots in one of its wells for the wickadjusting wheels and the wick -adjustillg wheels projecting into the wick-tube through these slots, of a projection formed on the slotted Wall of the wick-tube, whereby the wick is held away from the slots, substantially as set forth.

4. The combination; with the wick-tube having slots in one of its walls for the wickadjusting wheels and the wickadjusting wheels projecting into the tube through these slots, of a projection formed on the slotted wall of the wick-tube, whereby the wick is heid away from the slots, and projections formed on the opposite wall of the wick-tube I5 below the wheels, whereby the wick is held in reach of the Wheels when turned down, substantially as set forth.

Vitness my hand this lst day of July, 1889.
